The Wacker Neuson 5200018674 Primer is a genuine OEM component designed for the BS50-4As, BS60-4As, and BS70-4As series vibratory rammers. As a direct factory replacement, this primer is manufactured to the same specifications as the original part, ensuring proper fit and function within the fuel system. It is compatible across a wide range of BS-series rammer configurations, including standard, high-altitude, and GRX variants.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to exact original specifications, ensuring proper fuel delivery volume and bulb durability under repeated priming cycles.
- Direct Drop-In Replacement — Designed to install in the same mounting position as the original primer, with matching port sizing for a secure, leak-free connection to fuel lines.
- Broad BS-Series Compatibility — Fits BS50-4As, BS60-4As, and BS70-4As vibratory rammers across standard, high-altitude, and GRX configurations.
- Consistent Cold-Start Performance — A functioning primer delivers the precise fuel charge needed to start the engine quickly, reducing wear on the ignition system from repeated cranking attempts.
- Fuel System Safety — A cracked or degraded primer bulb can allow unmetered fuel to enter the carburetor or create a fuel leak at the connection point; replacing it with an OEM part restores correct sealed operation.
The primer is a small bulb or button in the fuel system that manually draws a measured amount of fuel into the carburetor before engine start. Pressing it purges air from the fuel line and gives the carburetor the initial fuel charge it needs for reliable ignition, especially after the machine has been sitting idle. When the primer cracks, stiffens, or fails to hold suction, starting becomes difficult or erratic, and fuel leaks at the bulb can become a hazard.
